Playing live at DTD .50/1. I am in hijack and facing one limper. I make it £5 with

. I am playing stack of £120
Button calls playing £140. He has played solid for about an hour. Only history we have is he bet then 4 bet me about half hour ago on alll club flop and i folded after i 3 bet. He was easy best in that particular spot as i was making a move. I get the sense he thinks i am picking certain spots but also pretty sure he thinks i am reasonably tight. I have been playing pretty straightforward since he sat down.
The limper also calls playing £60. He is playing fairly loose and pretty sure he just wants to get his money in and try and double.
