I just want some tips on my mental game. Basically, here's the problem: Last night, I was playing my dad in a set and I won it 6-2. I was playing quite well, I was serving and I was placing the ball pretty well, I was serving and volleying well, I was putting away probably every forehand bar one or two. And, I was killing him with my backhand up the line, I was hitting winners on the run and everything with the single handed backhand. We went down for a hit today, and he asked me if I wanted to challenge him, see he's No.3 in the club I play at and I had just put my name on the ladder about 7 months ago but hadn't challenged anybody so I was probably around 40th out of around 45. So, we played the challenge match, I lost the first set 6-4, one lapse in concentration on my serve and had the break, for some reason I couldn't get a hold of his serve at all, I couldn't get a good rhythm going on my returns. The second set at 4-4 I broke him to 15 and served it out to win the 2nd 6-4. And in the third I dominated him and won it 6-2 so I move up to No.3 in the club, there's something nice On the other hand, my forehand wasn't working at all. I couldn't control it and I wasn't hitting my usual winners, I was struggling to consistently get it back in play. So, at around 4-4 in the 2nd when I broke him I started using the reverse forehand on nearly every point I started creating loads of angles and really ripping it and it was controlled because of the extra topspin. This was probably the most important change I made in the match. My backhand on the other hand was disastourous. My usually consistent backhand and one that I love to rip up the line was "gone", it had "disappeared" over night. I was slicing for the first two sets and then in the third in one point, I hit a slice up the line to hit forehand, and then I hit a second one up the line, and then he played it to my backhand and for the first time I drilled a down the line topspin backhand winner and I did it again two points later. It had somehow "magically" reappeared for some reason. But my forehand was still not it's usual self. Does anybody know why this is? I think it's self-belief. I think sometimes that just before I go to hit it a small doubt pops into my mind that says "No, don't do that". But when it's not there it works brilliantly. Anyone know how to correct this? Strokes just don't disappear out of nowhere. And also my concentration is crap!! My definition of concentration is: I'm totally focused, I'm like 100% aware of what I'm doing, I'm not "thinking" about what I'm doing but I'm aware of what I am doing at all times. I'm also watching the ball all of the time. I seem to be able to "become aware" at will but can maintain it for like 2 seconds, usually as they start their service motion and then when they hit the ball it's gone again, lol.
