Um, master players do not have all of ability, too For instance,#0MASASAITOH of top player was not able to use t-spins. What's more, much to my surprise, he didn't so much as draw a line about the use of rotation related to directions. He did use the only "A" button. Nevertheless I was not able to compare with him. Beyond that, i know SEN/SEN and TGM-HOLiC didn't use TST too much. Moreover NOAH, too, didn't do when he was an active player. The rapid operation and t-spin techniques surely are important factors as was pointed out. However, to judging from precedent of many top players, I think these techniques are not all. The point is to have strong nose for survival. If player surpassed any other player in survival instincts, the player woundln't definitely lose?a match. I once heard SAMAF saying "the player who wins the digging race becomes a winner of games." Speaking to the extreme, we all have only to avoid "GAME OVER". I think you needn't learn t-spins yet cheer up!
