So I played a live mtt last night £60, it was a deep stack tournement like 70k chips blinds start at 100/200 and go up every 30 mins, after an hour I felt comfortable at the table apart from one player to my direct left of me, he was very loose and aggressive he had shown two three bet bluffs with stuff like 83 suited, with him being on my left he had position on me nearly every hand which made things difficult, also tbh I know a lot of people don't like to admit it but he was a better player than me, the money also didn't mean anything to him as he runs a successful business too and was just playing for fun and to win, if he had been on my right I think I would of had a lot better chance against him but nothing I could do about that. Is there any tips you guys could give me for situations like this as it's likely to happen again as he plays there every week?

tighten a little

then r/c and c/c him to death. keep his bluffs in. let him win when u miss. he'll give tons of value.

Thanks Man, I think that's where I was going wrong I tried to play back at him when I missed
