i thought that i may be able to find a call here. he was likely to be doing that with 9X and only 9A, 9K 9Q 93 98 had me beat, furthermore he was on the button. i beat slightly more than half his range.

the re-raise was rather big though. would this mean that he was more likely holding on to better hands?
