Last night I played a doubles league match with a partner I have never played before. During our warm up, my partner showed great skills, and especially had a strong serve. I was feeling very good about our chances with the match we were about to start. After our warmup, we changed courts to meet our opponents, and I noticed my partners demeanor changed: he looked a little nervous and his voice got quiet. We won the toss and I let him serve first since his serve in practice looked better than mine. His serves in the first game didn't have a third of the pace of his practice serves, and he woofed his first few shots, so we lost that game. After every point, I slapped hands with him to encourage him. As we changed sides, I really noticed how tight he was, and made considerable effort to pick him up. My partner's play improved as the match progressed, but was never as good as he normally plays. Despite that, we won the match. I felt like my biggest challenge during the match was encouraging my partner so he would relax and play the game I know he is capable of playing. So, my question is: How do you lift your partner when he/she gets tight and nervous?
